  • In this study, protective masks were designed in varying internal volume and analyzed in regards to wearing effect. Masks were measured by surface temperature and subjective wear evaluation. Four experimental masks were created with an increasing distance between the mask center line and nose in increments. The distances were set at 0.0 cm (M0), 2.0 cm (M2), 4.0 cm (M4), and 6.0 cm (M6). The area and volume of each experimental mask was measured and both measurements had a positive correlation with the set distances. Among the experimental masks, M2 was the most breathable. The heat between the face and the mask created by exhalation was able to escape from the mask and provided the highest comfort sensation when worn. Conversely, an internal volume that is too large would decrease its comfort because repetitive breathing deforms the appearance of the mask and adversely affects its fit. Therefore, creating and maintaining the optimal internal volume of the M2 mask is important to achieve maximum thermal sensation and ease of wear.
